I'm thinking #2/0 gauge is thicker cause its more expensive, am I correct? I really have no idea.

More copper means more money. However you difference is more in the application, how much voltage and the distance of the run.

Yeah, but which is thicker? #1/0 or #2/0?

I'm familiar with typical AWG wire gauge system, but they've thrown in #1 and #2.

#1 is thicker I believe.. This is one of those ass-backwards thing about wires.

Wait, apparently after 0 gauge wire the *second* number gets bigger as the wire gets bigger

http://en.wikipedia.org/wiki/American_wire_gauge#Table_of_AWG_wire_sizes

0000 (4/0) - 0.4600"
000 (3/0) - 0.4096"
00 (2/0) - 0.3648"
0 (1/0) - 0.3249"
1 - 0.2893"

Usually when the term "gauge" is used, a smaller number means larger.
There are some instances when that isn't true, i.e. guitar strings.

There is a difference between a #1 awg and 1/0. This table should help

Correct, once the 0/ or /0 gets added it is pronounce 1 aught, or aught 1.
